A Research On RFID Tracking-monitoring And Authentication Technology For The Gerocomium

The world will be full of the Internet of Things in the future. Radio FrequencyIdentification (RFID) is an important technology in the Internet of Things, and it is used toidentify the target objects automatically and apperceive every thing in the world through radiofrequency communication. Along with the people are ageing, the requirements of nursing andsupporting the elderly are more urgent in gerocomium, thus the health state of the elderlycome to be the focus in gerocomium for the managers and the families. To track and monitorthe activities of the elderly daily and reflect their health, the technology of RFID can beapplied. So the research for the tracking and monitoring by RFID is very significant. TheRFID applications for the elderly will settle the safety for nursing and the health state formonitoring, and develop its applications in the Internet of Things. It is important for theconstruction of the smart city, wisdom awareness and information digitalization to study theauthentication technology in RFID and its applications in tracking and monitoring areas.Based on the idea of designing a tracking and monitoring RFID system, this paper applies thehealth status prediction of elderly people, and carries out study on authentication technology in RFID.(1) A monitoring and tracking system based on RFID for gerocomium is designed. Thissystem is realized with the proper device type of RFID for monitoring and locating based onthe idea of the Internet of Things. The structure, monitoring function and database of thissystem is elaborated clearly. So fast positioning, real-time monitoring and response, andtimely nursing can be handled properly for the elderly, thus, the safety of elderly people ingerocomium and the work efficiency of managers are well improved.(2) The health status prediction method based on RFID data source for elderly people isstudied. As existing tracking and monitoring systems in gerocomium can not reflect the healthstatus of the elderly from their daily routine, on the basis of medical research and theconstruction of analytic function for elderly health, some health index indicating the healthcondition of the elderly is analyzed based on BP neural network, to predict the health status ofthe elderly and provide real-time and low-cost decision support for gerocomium management.(3) A RFID security authentication protocol based on Hash function is designed. Asexisting authentication protocols have various defects, an improved RFID mutual authenticationprotocol based on Hash function is proposed. This protocol solves the non-synchronousproblem in updating back-end data base and labels shared keys, reduces the exhaustive searchand Hash calculation in back-end database by using label location index, which furtherimproves the execution efficiency and scalability of RFID system, supports tag ownershiptransfer and is applicable for low-cost application environment with massive RFID tags.
